NOTICE
It’s unlikely that your new digital timer has any existing
programming, but to make sure, use this procedure before setting
the time.
Locate the Reset button. It is the small, round hole adjacent to the 1.
keypad. You will need a pen or paper clip to press this button.
Press and release the Reset button. The display will light up all 2.
the segments and then go blank.
The timer has erased all programming, displays the default 3.
settings (MO, “12:00 PM”) and is ready for setup.
3 – Clear Any Existing Programming
NOTE: The time, day AND operating mode must be set before any
ON Events can be programmed. Settings for time and ON Events
will not be activated until setup and programming are complete.
Setting Time and Day
Ensure that the time is displayed. A 1.
timer that is just reset will display
MO, “12:00 PM”.
The first two digits (hours) of the 2.
Time of Day (TOD) display will begin
to flash (Fig. 3).
Turn the selector wheel until the 3.
correct hour shows in the TOD hours
display, along with the PM indicator,
if desired. Note that PM indicator will
alternate on and off as the time
passes through noon and midnight.
Press the 4. ON button to set the new
hour. Or, if no change to the hour
is needed, press the TIME button to
keep the original hour setting. The
last two digits of the TOD display
(minutes) will begin to flash (Fig. 4).
